Abstract: Wireless broadcast advantage-based load-aware multi-channel multicast (W-LMCM) algorithm is proposed to solve the multicast routing and channel assignment problem with the goal of maximizing the number of served subscribers. W-LMCM regards links originating from the same node as a whole to fully exploit wireless broadcast advantage and save bandwidth; It uses maximal number channel selection strategy to avoid the adverse effect brought by random channel selection; While satisfying the channel capacity constraint within interference range, W-LMCM assigns channels for links with the goal of minimizing network interference, thus the problem that the number of subscribers served by interference-free channel assignment is limited can be solved. Network simulator simulation results show that W-LMCM can improve multicast throughput and network service capability efficiently.
